Specification of Letters Patent. Patented June 13, 1911.

Serial No. 527,220.

To all whom it may concern:

Be it known that I, WILLIAM HENRY Form, a citizen of the United States,resident of Niagara Falls, in the county of Niagara and State of NewYork, have made a certain new and useful Invention in Driers; and Ideclare the following to be a full, clear, and exact description of thesame, such as will enable others skilled in the art to which itappertains to make and use the invention, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

Figure 1 is a central vertical sectional view through the line 1-1 Fig.2. Fig. 2 is a horizontal sectional view through the line 22 Fig. 1.Fig. 3 a sectional view showing details, somewhat enlarged. Fig. 4; is avertical sectional detail view at the line 4..

The invention has relation to vertical cylindrical driers of the classdesigned for absorbing the surface water from grain or other granulargoods as it descends through an annular interspace or chute, and itconsists in the novel construction and combinations of devices ashereinafter set forth.

In the drawings are shown an exterior cyl inder 0,, having a slat-workwall, an interior cylinder Z), concentric therewith but separatedtherefrom and provided with perforations, and an exhaust connection withthe interior cylinder, which is movable. In the the cylinder casing a,is supported on a base frame 0, which is provided with a circularbearing d, of ball bearing type, on which rests the base 6, of theinterior cylinder 7), said base being of open or spider form and havinga concentric horizontal bevel-toothed wheel f, which is engaged by abevel pinion g, having its shaft bearing in the frame, and provided witha crank handle by the operation of which the interior cylinder may bemoved. The interior cylinder is separated from the exterior cylinder bya cylindrical interspace or drying chute 2, through which the grainpasses downward.

The wall of the exterior chamber a, is composed of series of upward andoutward sloping slats 1, which have a slight lap, said slats or reversedlouvers being secured to upright frame irons 2, which are secured attheir ends to the base e, and to a circular head it, which carries aboveit the receiving chamber 70, and the exhaust chamber Z, which surroundsthe receiving chamber and is'in communication with the interior cylinderby the ports m. From the exhaust chamber extends a pipe or pass-wayleading to an exhaust fan which may be located in any convenientposition. The top portion 8, of the inner wall of the receiving chamberis of conical or centrally raised form and is connected'to the portedcylindrical portion a, to form' a guide or spreader for the grainentering by the hopper throat i, to the circular chute a, between theinner and outer walls, through which it passes down into the interspace2, between the exterior and interior cylinders.

, The wall of the interior cylinder or cylindrical flue b, is providedwith series of perforations 5, of small size, and may be preferablyseries of narrow slots opposite the slate of the outer wall. Theseperforations are designed to be small enough to prevent the grain fromentering the interior cylinder.

At the upper end of the interior cylinder is secured a circular rim 6,which is provided with roller bearings 7, designed to move against acircular bearing 8, of the head It, and thereby facilitate movement ofthe cylinder while keeping it steady.

Below the cylinders in the base is a con centrating hopper 79,preferably of conical form, terminating in an outlet opening 9, which iscontrolled by means of a ball valve 8, adjustable by means of a leverdevice If.

Wet grain or other introduced into the receiving chamber and fallingupon its conical floor 3, is spread evenly and thus delivered to theannular chute a, through which it falls to the interspace 2, between theexterior and interior. cylinders, through which it continues its descentuntil obstructed by the ball valve which is designed to regulate theflow. Meanwhile the exhaust fan is continuously drawing air through thepassages between the slats of the outer cylinder and through the pass nggrain into the interior cylinder and carrying the moisture and vaporswith said air up and away. On account of the louver or slattedconstruction of the outer cylinder, the wet grain is apt to choke orstick in its downward way through the annular chute or interspace a,between the outer and inner cylinders, and in order to remedy thisdiflimaterial, having been culty and facilitate the movement of thegrain one of these cylinders, preferably the interior cylinder, is mademovable. In case of such choking of the grain a rotary movement of thecylinder will readily loosen the mass so that the grain will resume itsdownward movement.

The valve device for the outlet opening at the bottom of the hopperforms no part of my invention, and I disclaim the same.

Having described the invention, what I claim and desire to secure byLetters Patent 1s:-

1 A vertical drier having an exterior cylinder provided with series ofslat-work openings, and concentric therewith an interior perforatedcylinder, these cylinders being separated to provide an annularinterspace therebetween, a feed chamber communicating with the annularinterspace, an exhaust chamber communicating with the interior cylinder,anti-friction bearings at the upper end of one of said cylinders, asupport at its lower end and means for giving rotary motion to suchcylinder, substantially as specified.

2. In a vertical drier having an exterior cylinder provided with seriesof oblique slatwork passages, and an interior concentric cylinder havingperforations, these cylinders being separated to provide an annularinterspace therebetween, an exhaust chamber communicating withtheinterior cylinder, antifriction bearings at the upper end of theinterior cylinder, an annular bearing at the lower end of the same, andmeans for giving gotiiry motion thereto, substantially as specie Intestimony whereof I aifix my signature, in presence of two witnesses.
